DHCP vs Static
DHCP is an open, industry-standard protocol that reduces the complexity of administering networks using TCP/IP. It also provides a mechanism for automatically assigning IP addresses and reusing them when there are no longer needed by the system. It also provides associated configuration information when systems are first assigned IP addresses. DHCP has five key benefits to those managing and maintaining a TCP/IP network which are the following:
Centralized administration of IP configuration- DHCP IP configuration information can be stored in one location to enable the administrator to centrally manage it. The server tracks all leased and reserved IP addresses and list them in the DHCP console.
Dynamic host configuration- DHCP automates the host configuration process for key configuration parameters. This eliminates the need to manually configure individual hosts.
Seamless IP host configuration- The use of DHCP ensures that DHCP clients get accurate and timely IP configuration parameters without user intervention.
Scalability- DHCP scales from small to large networks and can serve ten clients as well as thousands.
Flexibility- Using DHCP gives administrators increased flexibility, allowing the administrator to more easily change IP configurations when the infrastructure changes.
DHCP relies heavily on broadcast messages. A DHCP relay agent is either a host or an IP router that listens for DHCP client messages. One purpose of the alternate configuration is as a solution for portable computers that move between a corporate, DHCP- enabled network and a home network where static IP addressing is used.
If you use DHCP with an alternate configuration, and the DHCP client cannot locate a DHCP server, the alternate configuration is used to configure the network adapter. No additional discovery attempts are made except under the following conditions: • The network adapter is disabled and then enabled again. • Media (such as network cabling) is disconnected and then reconnected.
• The TCP/ IP
